This script closes specified ports in Windows Firewall by setting the Enabled property to False, while retaining the stored port settings. To perform this task, it uses the Windows Firewall COM automation server. It runs only against the local computer.

ClosePorts-com.vbs does not correspond exactly to ClosePort.vbs, one of the scripts that ships with Application Compatibility Testing and Mitigation Guide for Windows XP Service Pack 2 and which are documented in the Appendix. Where ClosePort.vbs deletes an exception for only one port, ClosePorts-com.vbs disables but saves exceptions for multiple ports. You can download a Windows Installer (.msi) file that installs the Guide and its associated scripts from:

To use the script, copy the code, paste it into Notepad, and then save the script as ClosePorts-com.vbs. To run the script, open a command prompt window to the directory of the script and type:

cscript closeports-com.vbs

If the default script host on the computer is Cscript.exe, the initial "cscript" may be omitted.
